How to use mobile night vision equipment?

You can use it directly when you open it, and the effect is related to the hardware of the mobile phone;

The night vision device for mobile phones is enhanced by dark photography of mobile phone cameras, and the actual effect is not good.

Night vision device is a night vision device with image intensifier as the core device. When working, the infrared searchlight is not used to illuminate the target, but the reflected light of the target is used to enhance the visible image that the human eye can feel on the screen through the image intensifier to observe and aim at the target. Infrared night vision device is a military night vision device using photoelectric conversion technology.

It can be divided into two types: active and passive: the former uses infrared searchlights to illuminate the target and receives the reflected infrared radiation to form an image, while the latter does not emit infrared rays and forms a "thermal image" by relying on the infrared radiation of the target itself, so it is also called a "thermal imager".
